Yes! Check out Section 5.4 for LightGBM, Section 6.4 for XGBoost and Section 8.2.3 for CatBoost. In addition, the Case Studies for Chapters 5, 6, and 8 also contain examples of hyper-parameter selection.

Specifically, there are examples of how to perform cross validation for selecting learning rate & ensemble size along with early stopping for efficiency.
